The Ministry of Finance (MoF) was established in 4026 and was among the ministries represented on the first modern cabinet of the Royal Council at the Lorell Hall. It was founded to manage the financial transactions of the Hapan government, which had begun investing in foreign companies settling on Lorell. It has since been an important part of the Hapes Consortium, being responsible for monthly wages of all echelons of the government, Crown Corporations and the Royal Hapan Armed Forces, as well as acting as the government's treasury department and main accounting office.

The Ministry is also responsible for the planning of large financial projects together with the Office of the Prime Minister and Ministry of Industry, and has historically been in charge of issuing budgets to the members of the Royal League of Commerce. The ministry also manages trade affairs in cooperation with the Ministry of External Affairs and the relevant other government organizations. It has assimilated the Department of Trade to itself, once Trade had been downgraded from a ministry to a department, and after it was no longer deemed the best match to with the Ministry of Industry given its unrelenting growth in its focus areas.

Always having been the smallest of the traditional six ministries, during interludes between appointed ministers the ministry has no representation on the Royal Council, and it is instead headed by a career official from within ministry with the title of the Secretary of the Treasury, who answers to the Office of the Prime Minister and the Sovereign directly. Remarkably for a ministry of its age, only four individuals have held the ministerial reigns at the ministry during the past two decades; Steve "Falcon" Rainy, Carrie Jade, Aviana Badara, and Alley Trepe, perhaps thus underlaying the stability and growing economy of the whole of the Consortium.
